摘　　要：目的　运用组织多普勒成像 (DTI)技术观察冠心病的室壁运动情况。方法　用 DTI检测经临床确诊的 31例冠心病患者 (2 6例冠状动脉狭窄和 5例心肌梗死 )室壁运动和二尖瓣血流频谱 ,并与对照组进行比较。结果　冠心病组室间隔、左室侧壁及后壁的 E峰显著降低 ,A峰增高 ,E/ A值降低 ,二尖瓣口的多普勒频谱 E峰和 E/ A值与正常对照组比较无显著差异。 E峰减速时间 (DT)和 E峰时间 (ET)较正常对照组延长。结论　组织多普勒技术可较客观地反映冠心病左室壁舒张运动 。Objective To evaluate the left ventricular wall motion of patients with coronary artery disease(CAD) using Doppler tissue image (DTI).Methods DTI and pulsed Doppler mitral wave flow parameters were measured in 31 patients and the control group.All patients were confirmed by coronary angiography and on DTI in patients with CAD.Results Peak early diastolic velocity (E)and E/A ratio were significantly lower in coronary involved segments in comparison with the normal controls,E peak and E/A ratio of mitral flow were not significantly different in the two groups.ET and DT were significantly prolonged in CAD group.Conclusions Pulsed DTI measuring left ventricular segment is a valuable method to estimate patients with coronary artery disease.
